By Mayo Clinic staffHeart failure, also known as congestive heart failure (CHF), means your heart can't pump enough blood to meet your body's needs. Over time, conditions such as coronary artery disease or high blood pressure gradually leave your heart too weak or stiff to fill and pump efficiently.
You can't reverse many conditions that lead to heart failure, but heart failure can often be treated with good results. Medications can improve the signs and symptoms of heart failure and lead to improved survival. Lifestyle changes, such as exercising, reducing salt intake, managing stress, treating depression, and especially losing excess weight, also can help prevent fluid buildup and improve your quality of life.
The best way to prevent heart failure is to control risk factors and aggressively manage any underlying conditions such as coronary artery disease, high blood pressure, high cholesterol, diabetes or obesity.
